Vortices in a strongly interacting gas of fermionic atoms on the
BEC- and the BCS-side of the Feshbach resonance. At the given field, the
cloud of lithium atoms was stirred for 500 ms followed
by an equilibration time of 500 ms. After 2ms of ballistic expansion, the
magnetic field was ramped below the Feshbach resonance to 735G for imaging. The
magnetic fields were 740G (a), 766G (b), 792G (c), 812G (d), 833G (e),
843G (f), 853G (g) and 863G (h). The field of view of each image is
880mm · 880mm.(high resolution version)

A condensate of Fermion pairs (red) is trapped in the waist of a focussed Laser beam (pink). Two additional Laser beams (green) rotate around the edges to stir the condensate. Current-carrying coils (blue) generate the magnetic field used for axial confinement and to tune the interaction strength by means of a Feshbach resonance. After releasing the atomic cloud from the electromagnetic trap, the cloud expands ballistically and inverts its aspect ratio.
Resonant absorption imaging yields a density profile of the atomic cloud containing vortices.(high resolution version)

Vortices in Gases: Shown is a Vortex pattern in bosonic Sodium atoms (green cartoon) in a magnetic trap, Vortices in tightly bound Lithium molecules (red-blue cartoon) and a vortex lattice in loosely bound Fermion pairs created on the "BCS-side" of a Feshbach resonance. The background shows a classical vortex (Hurricane
